There are several=20 solutions: =2D Start with the driver available at http://cpm2usb.sourceforge.net/ and = port=20 it for your kernel. =2D Ask Montavista support for a CPM2 USB host driver (they will most likel= y=20 charge for that). =2D Buy the Arabella kernel and port the driver to the Montavista kernel (a= sk=20 the Arabella support to make sure their USB host driver supports what you=20 need, and pay attention to possible license issues). In the end, it boils down to writing code yourself or paying someone to do = the=20 job.
